CUTLERY-POLISHING MACHINEi Specification of Letters Patent.

Patented Oct.`9, 1906.

Application filed June 23,1904. Serial No. 213,829.

To all whom it may concern-.-

Be it known that I, CHARLES L. JOY, a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented certain new and 'useful Improvements in Cutlery-Folishing Machines, of which the following is a specification.

My invention relates to cutlery-polishing machines.

One obj ect of my invention is to so construct a machine that all of the important moving parts except the work-holder will be located to one side of the polishing-wheel, so that they can be covered and fully protected from the dust flying from the polishing-wheel. This and other objects will be more set forth and described in the following specification.

To enable others to understand my invention, reference is had to the accompanying drawings, in whichl Figure 1 is an upper plan view of the machine inclosed in a boX with the cover removed, broken view of the spring clamping lever or finger for the knife, and broken view of its spring. Fig. 2 is a front elevation of the machine with the front of the box or casing removed looking in the direction of arrow a of Fig. 1, broken view of the machine legs, and broken view of the sleeve and its supporting -rod connected with the work -holding mechanism. Fig. -3 is an end view of the machine and sectional view of its casing looking in the direction of arrow 't of Fig. 1, sectional view of the working sleeve and its supportingrod through linea of Fig. 1. Fig. 4 is an enlarged detail view of the oscillating support carrying the knife-holder, broken view of the sleeve to which said support is secured, and broken view of the rod on which said sleeve oscillates. Fig. 5 is an enlarged detailfront elevation of the support and knife holder looking in the direction of arrow c of Fig. 4. Fig. 6 is an enlarged side elevation of the slide in which the arbor or shaft of the polishingwheel is journaled, broken view of the polishing-wheel, and broken view of the bed of the machine. Fig. 7 is an enlarged end elevation of the Yoscillating support carrying the knifeholder and broken view of the polishing-wheel. Fig. Sis an enlarged detail sectional view of the knife-holder through line 't of Fig. 5. Fig. 9 is an enlarged detail sectional view of the knife-holder, clamping finger or lever for the particularly knife-handle through line c of Fig. 5. Fig. 10 is an enlarged detail sectional view of the knife-holder and neck of the knife-handle through line CZ of Fig. 5. Fig. 11 is a broken view, partly in section, of the knife-holder support.

The construction and operation are as follows: y

1 represents the bed of the machine. 3 and 4 are standards rising therefrom to s upport the driving-shaft 5; 6 is the drivingpulley, and 7 the loose pulley mounted on said shaft.

8 is a bevel-gear on one end of the drivingshaft and registering with the bevel-gear 9 on the short shaft 10, journaled in the standard 11.

12 is a crank-plate on the opposite end of shaft 10, to which one end of the connectingrod` 13 is pivoted, while the other end of said rod is pivoted to the stud 14, projecting laterally from the square sliding bar 15, which bar is caused to reciprocate through the rotation of the driving-shaft `5. 15L and 15b are supporting-standards for said bar. This bar 15 is made square in cross-section, not only to prevent its rotating, but this square form will wear better and can be kept from rotat-l ing easier than any other form.

16, Figs. 1, 2, 3, and 4, 1s a rod secured 1n the forward end of the bar 15, and 17 is a sleeve adapted to oscillate on this rod in the manner and for the purpose presently to be described.

The knife-holder support comprises the following elem'ents, viz: 18 and 19 are enlarged portions of the sleeve 17, and 20 and 21 are rods or stu'ds projecting therefrom.. 22 is a cross-bar having the hollow studs 23 and 24 secured to and projecting therefrom. These hollow studs 23 and 24 are adapted to slide on the studs 2O and 21 and carry the bar 22 with them. This bar is under the control of the spring 25, which spring tends to force the bar 22 outward as follows: 26is a rod supporting the spring 25, and this rod is journaled in the bracket portions 27 and 28 of the enlarged portions 18 and 19 of the sleeve 17. One end of the spring 25 is anchored in the collar 29 on the rod 26, and the opposite end 25@l lies against the grooved collar 30 on the cross-rod 31, secured to the enlarged portions 23a and 24a of the hollow studs 23 and 24. The tension of the spring 25 is increased or decreased by means of the handle 32 on the end of the rod 26 and the tension maintained by means of the pawl 33, Fig. 7, engaging the ratchet-wheel 34, secured to said rod.

35, Fig. 4, is the knife-holder, pivotally supported on the pin 36 of the cross-bar 22. 37 represents adjusting-screws carried by this bar to adjust the position of the knife-holder with respect to the polishing-wheel. The knife-blade 38 rests against the raised portion of the holder and is vertically supported at the neck 38a in the adjustable fulcrum 39, (see also Fig. 10,) and the blade is vertically adjusted by means of the screw 40 engaging the upper edge of the knife-handle 41.

42 is a stop for the end of the handle to rest against.

43 (see also Figs. 8 and 9\ is an adjustingscrew projecting laterally from the holder, the 4head 43EL of said screw forming a lateral support for the knife-handle. The adjustable fulcrum 39, engaging the neck of the knife, forms positive means for locating the knife-blade with respect to its support, while the adjusting-screws 40 and 43 afford ready and simple means for adjusting the blade.

44 is a clamp pivotally supported in the forked stud 45 and actuated by the spring 46 to engage the knife-handle during the operation of polishing the blade.

46E, Figs. 1, 4, and 7, is a rod attached to and projecting rearward from the cross-bar 22, passing through the lug 47 of the enlarged portion 18 of the reciprocating sleeve 17. The threaded end of this rod carries the adjusting thuinb-nut 48. This nut determines the extreme forward position of knife-holder. In other words, when the kiiife-blade is engaged by the polishing-wheel 49 the nut 48 will be away from the lug 47 and the knifeblade will be held against the polishing-wheel under the tension of the coiled spring 25, and when the knife-holder support has carried the finished knife out of contact with said wheel the nut 48 will check the further forward movement of the knife-holder. The polishing-wheel 49 is mounted on the end of the shaft 50, journaled, Figs. 1 and 6, in the standards 51 and 52 of the movable slide 53. rI his slide is made movable in order to position the polishing-wheel with respect to the position of the knife blade and the reciprocating knife-support. This ae'usted position of the polishingwheel is manually secured through the medium of the rod 55, its hand-wheel 56, and bevel-gear 57 on the rod 55 and the bevel-gear 58 mounted on the outer end of the short threaded shaft 59. The opposite end of the shaft 59 passes through the lug 60 of the slide 53 and into the standard 52 of said slide. The polishing-wheel shaft has the tight and loose pulleys 501 and 50h, by which said shaft is run independent of the rest of the machine.

The oscillating movement of the knife-sup- 6 5 port is acquired as follows: 61, Figs. 1, 2, and

3, is a cam indirectly connected with the driving-shaft 5, and 62 is a roll mounted in the end of the swinging lever 63, which lever is pivotally supported to the standard 64, projecting from the machine-bed. 65 is a transverse plate secured to this lever to be engaged bv the roll 66 on the end of the arm 67, projecting from the clamp-collar 68. se-

cured to the sleeve 17.

When the machine is in operation, the cam 61 will lift the lever 63 and carry the knifeholder in the direction of arrow e, Fig. 7, and when the roll 62 is on the highest part of the cam 61 all of the moving parts of the machine except the polishing-wheel are brought to a standstill, as follows: 69, Figs. 1, 2, and 3, is a shipper-rod movably supported in the standards 70 and 71. 72 is the shipper, connected to said rod, through which the belt (not shown) passes. 73 is a short trip-lever pivotally supported on the end of the stud 74, projecting from the shipper-bar 69. 75 is a trip-pin in the end of the trip-lever 73, and 76 is a standard to support said trip-lever. 77 is a shipper-lever pivotally supported on the shipper-rod 69, by which said rod is operated. Moving the lever 77 in the direction of arrow f, Fig. 1, will carry the belt onto the tight pulley 6 and rotate the drivingshaft 5. The notch 73a, Fig. 2, on the under side of the trip-lever 73 will engage with the forward edge of the standard 76 to hold the shipper-rod temporarily in its forward position. When, therefore, the arm 78, Fig. 3, of the cam 61 strikes the end of the trip-pin 75,

v it will lift the trip-lever 73 sufficient to disengage its hold onl the standard 76 and bring the shipper-rod 69 under the influence of the spring 79, Figs. 1 and 2, and carry the drivinv-belt over onto the loose ulley 7 and bring the driving-shaft and sli ing bar 15 to a state of rest. The spring 79 is on the shipper-rod between the collar 80 and the standard 70 to pull, as before mentioned, the shipper-rod back, while the short spring 81, located between the collar 82 and 'the opposite side of said standard, will act as a buffer to prevent a too sudden stoppage of the shipperrod. When the roll 62, Fig. 3, is on the highest part of the cam '61, the oscillating support, carrying the knife-support, will be at its highest point, as shown at Fig. 7. While in this position the finished knife is removed from the holder and another secured thereto. Then when the cam 61 begins to rotate the roll 62 will drop and allow the knife-holder to fall so as to begin its upward movement to polish the knife, and when the arm 78 en- Gages the tripin 75, before mentioned, the fiirther upwar movement of the knife-holder support will cease. The pin 75 is made adjustable, so that the driving-shaft can be stopped sooner or later, as desired.

lt being advisable to rotate the cam 61 at a lower rate of speed than the driving-shaft 5,

IOC

IIO

the motion of said cam is reduced as follows z' 83, Fig. 1, is a gear rigidly mounted on the ,lateral projection 4a of the standard 4 and its cap, it being understood that the gear 83 surrounds the driving-shaft 5, but not in contact with it. 84 is another gear loose on the shaft, and on a reduced portion of this gear 84 is rigidly secured the cam 61. 85 is a planet-pinion registering with the gear 83, and 86 is another planet-pinion registering with the gear 84. These planet-pinions are secured to a short rotatable shaft (not shown) in the sleeve 87, and 87a is an arm of said sleeve secured to the driving-shaft. The gear 83 has one more tooth than gear 84, so that when the planet-pinions 85 and 86, carried by the driving-shaft, have revolved about the pinions 83 and 84 the cam 61 will have been rotated a distance represented by one tooth of the gear 83.

The principal-working parts of the machine most susceptible to wear from the flying articles of emery are arranged far enoug to one side of the polishing-wheel so that they can be inclosed by the casing 88, resting on the bed of the machine, the to not being shown, the rod 16, carrying the s eeve 17 and knife-holder support, being the only part of the machine projecting outside of the casing 88. The rod 16 is so completely protected by its long sleeve that no emery could reach it to do any harm.

O eration: A knife is placed on the knifeholdlcr when the holder is elevated,l as before mentioned, and when the driving-shaft is started to rotate the knife-holder support is caused to drop to carry the knife below the continuously-running polishing-wheel to be polished on its return movement, and when the cam actuating the sleeve carrying the knife-support has reached the highest point all of the moving parts of the machine, eX- cept the polishing-wheel, are automatically brought to a state of rest, the finished knife is removed and replaced by another, and the machine restarted.
